NEW DELHI, June 17, 2025 (BSS/AFP) - India on Tuesday urged its citizens to leave Tehran, while some nationals have already fled across the Iranian border as the country comes under Israeli bombardment.

With Israel vowing to keep up its attacks four days after launching its assault on Iran, which has launched retaliatory strikes, New Delhi said Indian students have already left Tehran.

"Residents who are self sufficient in terms of transport have also been advised to move out of the city in view of the developing situation," the foreign ministry said in a statement.

The warning came after Israel's ally US President Donald Trump said "everyone" should "immediately" leave the Iranian capital, which is home to nearly 10 million.

New Delhi said "some Indians have been facilitated to leave Iran through the border with Armenia", hundreds of kilometres (miles) northwest of Tehran.

The foreign ministry did not detail how many of its citizens have been affected in Iran, where there are around 10,000 Indians according to government data last year.

Thousands of Indians are also in Israel, and New Delhi has issued warnings for its citizens there to "stay vigilant".
